My brother and I recently put a budget pc together. We waited a few days until everything arrived. But when I looked in the case there were no screws or other thing put in the case and you have to add the power supply above the motherboard. There isn't even a little platform that holds the power supply up. Just a small thingy from the case. I came to the conclusion that you just had to screw the power supply to the bracket. But the case came without screws. Is there any way to fix this problem because I have no clue.
